Firstly, the mathematical results on which it is based are presented and the existing attacks against it are analyzed. Finally, a practical implementation of the cryptosystem and four of its attack is carried out, from which experimental results are extracted.76 p.application/pdfcatmemòria: cc-nc-nd (c) Miquel Guiot Cusidó, 2022codi: GPL (c) Miquel Guiot Cusidó, 2022http://www.gnu.org/licenses/gpl-3.0.ca.htmlhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Teoria dels reticlesCriptografiaProgramariTreballs de fi de grauTeoria de nombresLattice theoryCryptographyComputer softwareNumber theoryBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
